(a) Water supply company in West Africa delivered an annual quantity of 80 million m3 to a city of 12 million households. Analyze the specific water demand in the distribution areas
Reservoir and Streamflow Routing
In hydrology, a reservoir is usually a natural pond that is enlarged or made using a dam to keep the water clean. Reservoirs or dams can be constructed in several ways, including controlling the existing watercourse, disrupting the watercourse to form embayment within it, by digging or building any number of retaining walls.
Water Resource Systems Analysis
Water resources are natural water sources that may be as useful as water sources. 97% of the world's water is saltwater and only 3% is pure water; just over two-thirds of this ice sheet is located in glaciers. The remaining pure frozen water is found primarily as groundwater, with only a small fraction present above the ground or in the air. Natural sources of freshwater include surface water, under river flow, groundwater, and ice water. Artificial water sources can include treated wastewater (recycled water) and saline seawater.
QUESTION 1
- (a)
- Water supply company in West Africa delivered an annual quantity of 80 million m3 to a city of 12 million households. Analyze the specific water demand in the distribution areas
- b)
- Examine the domestic consumption per capita of 12 million households with leakage from the system estimated to be 15 % of the total water supply and billed non-domestic consumption of 20 million m3/year
- (c)
- In a residential area of 250, 000 people, the specific water demand is estimated at 150 l/c/d which includes leakage.
- (i) Evaluate demand in 20 years if the assumed annual demand growth is 2.5 %.
- (ii) Applying both the linear and exponential models in estimating water demand.
